Here are some links worth watching and reading, I'm happy to provide you with what I know, fortunately, these links do not go into the who, but rather objectively ask questions via the scientific method why the official narrative is impossible:

When you, if you, come to the conclusion that 9/11 was an intelligence job as were the Anthrax attacks, then you can research who was behind it:, and it does become quite obvious who was behind it. I for the longest time laughed at the possibility that 9/11 was an intelligence job but researching and reading Graeme MacQueen, Christopher Bollyn and David Dray Griffin's among others books and studies has changed my mind, forever.

Keep in mind, there are agents within the truth movement, hundreds of agents. Cass Sunstein, a Zionist made it clear, that agents would have to be hired to create infighting in the 9/11 truth movement to break it up. Hence, these agents introduced disinformation theories such as the no plane theory, the space weapon theory, the Judy Wood theories, the nuke theories, all are cognitive infiltration of the real truth. That the towers were brought down with various explosives, sol-gel-nano-Thermite, gelignite, detcord and possibly C4 on the core beams which are easily accessible through the elevator shafts and which had major projects just before 9/11 by a company, now defunct that specializes in demolitions (ACE and Lvi).
